Transgene has been a shareholder in Tasly BioPharmaceuticals since August 2018 when it received

27.4 million shares of Tasly Biopharmaceuticals in exchange for the sale of the Greater China rights of T101 and T601, two products respectively incorporating Transgene's TG6002 and TG1050 patented technologies. At the time, these shares were valued at $48 million based on the pricing of a funding round conducted by Tasly concurrently with Transgene's share subscription compared to the pre-IPO value of $59 million implied by the current operation.
